Liquid reservoir evacuation apparatus and method

Abstract

An improved liquid reservoir evacuation apparatus and method including a fixture with a venturi valve. A first liquid reservoir where the first liquid reservoir has an outlet. A first on/off valve connected with the first liquid reservoir outlet. An air intake with a first section and a second section where the first section of the air intake allows air outside of the fixture into the fixture and the second section connects the first on/off valve with the venturi valve, intersecting the venturi valve and exiting the fixture at an exit. A second liquid reservoir with an outlet connected with the fixture exit. A second on/off valve connected with the second liquid reservoir outlet and a third on-off valve connected with the fixture such that liquid flow from the second end is allowed or prevented.

What is claimed is: 
     
       1. An improved liquid reservoir evacuation method consisting of:
 a. providing a fixture with a first end and a second end and a venturi valve with an inlet with a diameter and an outlet with a diameter wherein said inlet has a smaller diameter than the diameter of said outlet; a first liquid reservoir configured to contain a liquid wherein said first liquid reservoir has an outlet; a first on/off valve connected with said first liquid reservoir outlet, wherein said first on/off valve is configured to open and shut the connection with said first liquid reservoir outlet and an air intake with a first section a second section wherein the first section of said air intake allows air outside of said first on/off valve into said fixture and wherein said second section connects said first on/off valve with said venturi valve transverse to said inlet and outlet, intersecting said venturi valve at said smaller diameter inlet and exiting the fixture at an exit; a second liquid reservoir connected with the fixture exit, configured to contain a liquid wherein said second liquid reservoir has an outlet; a second on/off valve connected with said second liquid reservoir outlet, wherein said second on/off valve is configured to open and shut the connection with said second liquid reservoir outlet and a third on-off valve connected with the fixture such that liquid low from the second end is allowed or prevented: 
 b. connecting said first end of said fixture to a fluid source: 
 c. closing the first on-off valve and third on-off valve; and 
 d. opening the second on-off valve so as to add fluid from said fluid source to said second liquid reservoir. 
 
     
     
       2. The method of  claim 1  further including:
 a. adding liquid to said first liquid reservoir; and 
 b. adjusting said first on/off valve to open the connection with the liquid reservoir outlet. 
 
     
     
       3. The method of  claim 1  wherein the liquid in the first liquid reservoir is selected from a group consisting of: emollients, skin conditioners, liquid soup and medicinal applications. 
     
     
       4. The method of  claim 1  wherein the liquid in the second liquid reservoir is selected from a group consisting of: emollients, skin conditioner, liquid soap and medicinal applications. 
     
     
       5. The method of  claim 1  wherein the fixture is configured as a shower head for use in a shower.
